Unfortunately, this only works when the number of reviewers is 
high and they review everything. Phobos contributions have about 
four regular reviews and about ten people who review on and off. 
I can't blame people for not reviewing things at once, because 
the things that I review take a while for me to get through 
because I find the process a little tedious (not a D/Phobos 
specific thing, it's just about looking at other's code). I 
usually allow for two weeks before I ping someone because of this.

The PR of mine you referred to had serious problems on it's first 
implementation and should not have been pulled in 36 hours. There 
was even a whole form discussion about it:

While I would love nothing more than for reviewing to go faster, 
I can't think of any mechanism to force reviews and contributors 
to respond faster to comments/make comments.

On a more positive note, trivial changes usually are merged 
within two days.
